Frequently Asked Questions- Triplex Parallel Lashed Aerial Cable (PLAC)


How Am I going to Identify Triplex Parallel Lashed Aerial Cable (PLAC)?
First, look at the number of conductors in the cable. They should be three, however, two of them are concentrically stranded and they are made of compressed aluminum. The third wire which runs outside of the two and is bare conductor made of aluminum alloy or steel reinforced aluminum conductor (ACSR). This third wire acts as the neutral support. Another thing you look at is the insulation. It is made of extruded cross-linked polyethylene that is lead free. You will also see a binder wire or lashing wire which is also made of aluminum alloy and insulated using high density polyethylene. The binder wire holds the three conductors together. 

How is the engineering of Triplex Parallel Lashed Aerial Cable (PLAC)?
An insulation of cross-linked polyethylene is used to provide protection against abrasion, cutting, chemicals, sunlight, weathering and tearing. The XLPE insulation is also lead free for safety of installation and people in the location where the wires run.

Where can I use Triplex Parallel Lashed Aerial Cable (PLAC) 
You can use this cable for secondary overhead power distribution. It is used in transmitting single phase power in buildings or structures. 

My installation has a temperature rating of 75 degrees Celsius, what option of PLAC wire do I have?
While Triplex Parallel Lashed Aerial Cable (PLAC) is intended for use in low voltage applications of 600 volts and operating temperatures of 90 degrees Celsius, you may get an alternative cable designed for operating temperatures of 75 degrees Celsius. The alternative cable may have an insulation made of polyethylene or high-density polyethylene (HDPE) in case you will have underground installations or where risks of damage to the XLPE insulation may be present for aerial installations.
